Add hs.styledtext support to hs.chooser

[latenitefilms]

@cmsj - I was thinking about using hs.chooser as a font selection tool. Is it possible to add hs.styledtext support to hs.chooser?

To clarify, it would be great if the "text" and "subText" for each individual "choice" could be a hs.styledtext object - so that I could use hs.chooser as a font selection tool (i.e. each result will be displayed as a different font).

@latenitefilms do you mean to the search box, or the results?

[latenitefilms]

Results would be amazing!

@cmsj & @asmagill - I'm happy to give this a bash myself if one of you can point me in the right direction?

Note to self:

NSAttributedString *theStr;
if (lua_type(L, 1) == LUA_TUSERDATA && luaL_testudata(L, 1, "hs.styledtext")) {
	theStr = [skin luaObjectAtIndex:1 toClass:"NSAttributedString"];
}

So, I think the branch I just pushed should address this, but I can't get it to actually do anything. I can see from the debugger that NSAttributedString objects are making it into the NSTableView delegate methods and being set on the choice cells, but my quick experiment with it doesn't work:

             else
                 choice["text"] = name
             end

I've never used hs.styledtext before - am I doing something wrong with it?

@latenitefilms maybe you could try my branch and let me know if you get any luck with it?

@cmsj - Soooooooo close! The subText works, but the text doesn't.

Maybe this line is the issue?

Here's my testing code:

local chooser = require("hs.chooser")
local console = require("hs.console")
local inspect = require("hs.inspect")
local styledtext = require("hs.styledtext")

local completionFn = function(result)
	print(string.format("Result: %s", result and inspect(result)))
end

local fancyText = styledtext.new("First Choice", {
        color = {hex = "#FF0000", alpha = 1},
        font = { name = "Futura", size = 20 },
    })

local fancySubText = styledtext.new("This is the subtext of the first choice", {
        color = {hex = "#FF0000", alpha = 1},
        font = { name = "Futura", size = 20 },
    })

console.printStyledtext(fancyText)
console.printStyledtext(fancySubText)

local choices = {
	{
		["text"] = fancyText,
		["subText"] = fancySubText,
		["uuid"] = "0001"
	},
	{ 
		["text"] = "Second Option",
		["subText"] = "I wonder what I should type here?",
		["uuid"] = "Bbbb"
	},
	{ 
		["text"] = "Third Possibility",
		["subText"] = "What a lot of choosing there is going on here!",
		["uuid"] = "III3"
	},
}

theChooser = chooser.new(completionFn)
	:choices(choices)
	:show()

Ummm... I'm not sure what's going on. The code you've added definitely seems to get setting text to
an NSAttributedString. Something must be happening to it AFTER - (NSView *)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row?
